Hi guys,
I have a problem with showing double Axis's title.
Could you please give me some advice?
the source code as follows:
-----------------------------------------------------------------------------------------------------------------
<html>
<head>
<script type="text/javascript"
src="https://www.google.com/jsapi";></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'date');
data.addColumn('number', 'rate1');
data.addColumn('number', 'rate2');
data.addColumn('number', 'rate3');
data.addColumn({type:'string', role:'annotation'});
data.addColumn('number', 'rate_avage1');
data.addColumn({type:'string', role:'annotation'});
data.addColumn({type:'boolean', role:'certainty'});
data.addColumn('number', 'rate_avage2');
data.addColumn({type:'boolean', role:'certainty'});
data.addColumn({type:'string', role:'annotation'});
data.addRows([
['12/11',0.0011,0.004,0.94,'94%',0.0019,
'0.19%',false,0.0042,false,'0.42%'],
['12/12',0.0013,0.003,0.93,'93%',0.0019, null
,false,0.0042,false, null],
['13/1' ,0.0018,0.002,0.91,'91%',0.0019, null
,false,0.0042,false, null],
['13/2' ,0.0015,0.005,0.95,'95%',0.0019, null
,false,0.0042,false, null],
['13/3' ,0.0021,0.006,0.96,'96%',0.0019,
'0.19%',false,0.0042,false,'0.42%']
]);
var options = {
title: 'rate show',
legend:{position:'top',maxLines:1},
seriesType : "bars",
vAxis:{format:'#,###.#%'},
format:'#,###.#%',
series:{0:{color:'blue',targetAxisIndex:1},
1:{color:'green',targetAxisIndex:1},
2:{type:"line",color:'red',pointSize:'5',targetAxisIndex:0},
3:{type:"line",visibleInLegend:
false,pointSize:'0',color:'blue',targetAxisIndex:1},
4:{type:"line",visibleInLegend:
false,pointSize:'0',color:'green',targetAxisIndex:1},
vAxes:{0:{title:'R1'},1:{title:'R2'}}}
};
var chart = new
google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</head>
<body><div>
<div id="chart_div" style="width: 800px; height: 400px;"></div>
<div>
</body>
</html>
